The IDP itself sets a minimum age of 18 for issuance, but that minimum is only the first age threshold a foreign driver encounters. Destination countries enforce their own minimum ages for foreign drivers, and rental agencies enforce their own commercial minimums and maximums on top of the national rules. The three-layer age framework produces situations where a 19-year-old US driver with a valid IDP can legally drive in a destination but cannot rent a car, or where a 75-year-old foreign driver faces no legal age cap but cannot rent without supplemental insurance. This guide walks all three layers.
What is the minimum legal age to drive abroad with an IDP?
The minimum legal age to drive abroad with an International Driving Permit is determined by three layers: the IDP's own minimum age (18 under the 1949 Geneva Convention and 1968 Vienna Convention), the destination country's minimum driving age for foreign visitors (commonly 18 or 21), and the rental agency's commercial minimum age (commonly 21 or 25 with under-25 surcharges). The highest of the three minimums applies — typically the rental agency's commercial cap for car rental purposes.
A 17-year-old with a valid US license cannot obtain an IDP at all because the IDP's own minimum is 18. An 18-year-old with an IDP can legally drive in most destinations but generally cannot rent a car from major brands until age 21 or 25.
Why does the IDP set a minimum age of 18?
The IDP sets a minimum age of 18 because the 1949 Geneva Convention on Road Traffic specifies this minimum as a uniform standard for international driving certification, independent of national licensing minimums. Some countries (United States, Canada, Australia, the United Kingdom) allow national driver's licenses at age 16 or 17 with full or restricted privileges, but those licenses cannot be translated into an IDP until the holder turns 18.
The 18-year minimum is non-negotiable by national issuers. A 17-year-old US driver with a full state license must wait until their 18th birthday to apply for an IDP.
What are the minimum driving ages for foreign visitors in major countries?
Minimum driving ages for foreign visitors in major destinations include 18 in most EU countries (with some imposing 21 for car rental), 18 in the United Kingdom (21 for most rental brands), 18 in Japan (with destination-cap rules), 21 in the United Arab Emirates, 25 in Saudi Arabia for rental purposes, and 18 in most of Latin America. The minimum legal age is typically lower than the rental-commercial minimum, creating the gap between "legally allowed to drive" and "able to rent a car."
Some destinations apply different minimums to foreign visitors than to residents. France allows national driving at 18 but recognizes foreign visitors' driving from age 18 only if their home country also permits driving at 18, an unusual reciprocity rule that catches young US drivers from states with 16-year-old minimums.
What are the rental car age requirements abroad?
Rental car age requirements abroad are set by individual rental brands and typically include a minimum age (commonly 21, with under-25 surcharges of $20–$40 per day) and a maximum age (commonly 75 or 80, with over-70 surcharges and supplemental insurance requirements). Premium vehicle classes (luxury cars, SUVs, vans) often impose higher minimum ages of 25 or 30 regardless of the destination's national rules.
The big four international brands — Hertz, Avis, Europcar, Sixt — apply broadly similar age rules across their European, Middle Eastern, and Asian fleets, with country-specific variations. Local rental brands in some destinations apply more flexible rules but offer less consistent vehicle quality and insurance coverage.
What is the under-25 surcharge?
The under-25 surcharge is a daily fee imposed by most international rental brands on drivers aged 21–24, ranging from $20 to $40 per day depending on the destination and vehicle class. The surcharge reflects insurance actuarial data showing higher accident rates for under-25 drivers and is generally non-negotiable through standard booking channels. Some rental brands waive the surcharge for corporate-account renters, AARP/AAA members in the US, and certain credit card holders.
The surcharge applies even when the driver presents a valid IDP and meets the destination's minimum legal age. The IDP does not exempt the holder from age-based rental policies.
What is the maximum age for driving abroad?
There is no maximum legal age for driving abroad under the 1949 Geneva or 1968 Vienna Convention. The IDP is issued without an upper age limit, provided the applicant holds a valid national driver's license. Some national licensing authorities impose age-related medical testing requirements (UK drivers over 70 must self-certify every 3 years, French drivers over 70 must pass medical reviews), and these national requirements transfer to the IDP — an expired national license voids the IDP regardless of age.
Rental agencies typically apply maximum age caps of 75 or 80 with supplemental insurance, medical-fitness questionnaires, and limited vehicle class options. The maximum age caps are commercial rather than legal — a 78-year-old driver may legally drive in a destination but be unable to rent from major brands.
Do any countries restrict foreign drivers based on age?
A small number of countries impose foreign-driver-specific age rules that differ from their resident driving rules. The United Arab Emirates requires foreign drivers to be at least 21 for car rental and 25 for premium vehicle classes. Saudi Arabia requires foreign drivers to be at least 25 for most rental contracts. Some Pacific island nations impose foreign-driver minimum ages of 23 or 25 regardless of the home country's minimum.
These foreign-driver-specific rules are enforced at the rental counter rather than at the border, and they override the destination's general resident driving rules.
For drivers holding non-US licenses
UK drivers face the same three-layer age framework. UK rental brands often have lower minimum ages (17 for some local brands, 18 for most international brands) than US-based foreign drivers face in the UK. EU drivers within the EU face member-state-specific minimums, with most EU countries setting 18 as both the national and rental minimum. Canadian drivers face a 16-year-old national minimum in most provinces but the 18-year IDP minimum still applies. Australian drivers face state-by-state minimums and the same 18-year IDP minimum.
The IDP minimum age of 18 is universal across all license origins.
Key Takeaways

- Destination countries enforce their own foreign-driver minimums, commonly 18 or 21.
- Rental agencies typically require 21+ with under-25 surcharges of $20–$40 per day; premium classes require 25 or 30.
- There is no maximum legal driving age abroad, but rental agencies cap at 75 or 80 with supplemental insurance.
- Some countries (UAE, Saudi Arabia) impose foreign-driver-specific age rules that differ from resident rules.
- Age-based medical testing requirements transfer from the national license to the IDP.
Frequently Asked Questions
Can a 17-year-old with a US license drive abroad with parental supervision?
No. The IDP's 18-year minimum applies regardless of supervision. A 17-year-old cannot obtain an IDP and therefore cannot legally drive in any destination that requires one. Parental supervision does not extend a minor's domestic driving privileges across borders.
Does the under-25 surcharge apply to all rental brands?
Most international brands apply it; some local brands in select destinations do not. The surcharge is also waived for some corporate accounts and credit-card-bundled rentals. Confirm at booking, not at the counter.
Can I drive on my IDP after turning 80 abroad?
Yes, provided the national driver's license remains valid. Rental access may be limited, but the legal authority to drive on the IDP continues as long as the underlying national license remains active.
